 \section{Segmentation}
 
 Sensitive volumes in a calorimeter detector usually require virtual subdivision in order that energy depositions can be accumulated into cells.  This concept of dividing geometric volumes is modeled by specific concrete implements of the \textit{segmentation} element.  This algorithmic rather than geometric approach to segmented readout has other advantages.  Modeling millions of individual cell volumes could be prohibitive in terms of memory usage. There are also cases in which modeling a readout system with an algorithm rather than geometry is more simple, such as in projective towers where there are many different shapes and sizes of cells which would be complicated to model using only solids and volumes.

+Concrete segmentation types extend a basic abstract element, which has no attributes.  The names of the parameters which define the dimensions of the cells are specific to a certain type of segmentation.  The segmentation element occurs as a child of the calorimeter sensitive detector.  Each calorimeter may have one of these associated objects.  The values of the fields from the segmentation at a certain hit position can be written in the identifiers of the hits by referencing their names.

-All segmentation elements extend a basic type which has no attributes.  The parameters defining the size of the cells are specific to the sub-type of segmentation.  This element is a child of the calorimeter that will use it, and each calorimeter detector is allowed to have one of these.  The implementation classes define names that can be referenced in identifier descriptions for writing the cell field values at a certain position into the output identifiers of the hits.  These are called bin values because they are similar to histogram bins.
